Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to an automobile anti-escape system. Background Art

[0002] At present, some gas stations have the phenomenon of refueling and escaping, which causes losses to the gas stations and requires the use of public resources to track them down, increasing unnecessary police investment. In addition, in police work, when it is necessary to intercept the target vehicle, they usually set up railings or arrange tire puncture spikes to intercept it, which causes certain damage to the vehicle.

[0003] For example, Chinese patent CN209482203U discloses an anti-escape device installed in a highway toll booth. The device includes a movable steel plate, hollow steel plate A, hollow steel plate B, a pressure sensor, a stepper motor, a screw cylinder, and a controller. When the guardrail is struck by a certain force, the pressure sensor transmits a pressure value. When the pressure value received by the controller exceeds a threshold, the controller controls the rotation of the rotary motor, further contracting the screw cylinder, thereby pulling the movable steel plate into hollow steel plate A, thereby revealing a pit. The rear wheels of a vehicle, slowed by impacting the guardrail, fall into the pit and stop moving, causing some damage to the vehicle. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a car anti-escape system to achieve the purpose of effectively preventing the car from escaping without damaging the vehicle.

[0025] The specific implementation of the present invention will be further explained in detail below through description of embodiments with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the automobile anti-escape system includes a platform structure, a rotatable roller structure corresponding to the front and rear wheels of the automobile, and a limiting structure for limiting the rotation of the roller structure; a groove is provided on the platform structure, the roller structure is arranged in the corresponding groove, and the limiting structure is arranged corresponding to the end of the roller structure.

[0027] The platform structure includes a vehicle body load-bearing platform 8 and an approach step 9 and a departure step 10 provided at both ends of the vehicle body load-bearing platform; a groove is provided on the vehicle body load-bearing platform; and the step surfaces of the approach step and the departure step are both inclined surfaces.

[0028] The drum structure includes a support shaft 14, a support base 15 and a drum ring. The drum ring is arranged on the support shaft through the bearing inner core 5. The support base is arranged on the side of the platform structure, and the end of the support shaft is arranged on the support base on the corresponding side; the drum ring includes a front drum ring 11 and a rear drum ring 6. The front and rear drum rings are arranged in the same way, and the distance between the front drum ring and the rear drum ring can be adjusted as needed.

[0029] The roller ring can rotate without restriction. The roller ring is larger than the tire and can support the tire. The tire and the roller ring are in a relative sliding state, which dissipates the driving force and thus limits the movement of the car.

[0030] Preferably, the limiting structure includes a limiting member, a driving structure for driving the limiting member to move, and a roller limiting tooth provided on the end of the roller structure. The limiting member is connected to the driving structure, and one end of the limiting member is provided with a tooth structure that can cooperate with the roller limiting tooth.

[0031] The roller structure end is provided with a roller limiting gear 10, which is easy to install. The limiting member is an L-shaped structure, and the driving structure and the limiting member are both arranged below the roller structure, which is compact.

[0032] The driving structure is a limit motor 1, a driven gear 2 is provided on the rotating shaft of the motor, and a spur gear structure 3 matched with the driven gear is provided on the limit member.

[0033] The present invention also includes a controller for controlling the operation of the motor. Corresponding limiting structures are provided at both ends of the drum structure. The controller is connected to the motor, and the control is simple.

[0034] In the present invention, when the anti-escape function is turned off, the limit motor 1 receives the off function signal, starts the motor, and transmits power to the driven gear 2 through the motor drive shaft 13. The driven gear drives the limit member to move, driving the limit gear structure 4 to approach and enter the interior of the roller limit gear 10, achieving a fixing effect. This limits the rotation of the bearing inner core 5, and achieves the purpose of maintaining the front roller ring 11 and the rear roller ring 6 in a fixed position. In this way, when the vehicle passes the approach step 9 and drives to the front roller ring 11, the front roller ring 11 is limited, so the wheel adhesion can be maintained, allowing the wheel to continue forward and enter the vehicle body load platform 8. When the vehicle is deployed, when passing the rear roller ring 6, it is synchronized with the front roller ring to limit the position. This allows the wheel to maintain friction and can drive forward normally, and the vehicle deployment is completed after passing the departure step 7.

[0035] Among them, the front drum ring and the rear drum ring are fixed at the top through the internal support positioning shaft 12 and the support shaft 14, and the base is fixed through the support base 15.

[0036] When refueling, anti-runaway mode is disabled by default. This allows the vehicle to maintain wheel traction as it approaches the steps and reaches the front rollers, which are positioned to prevent the vehicle from moving forward onto the vehicle's loading platform. Once the vehicle is on the platform, anti-runaway mode is activated. The front and rear rollers are now in sliding mode. If you refuel without paying and continue driving forward or backward, the sliding action of the front and rear rollers will neutralize the driving force and secure the vehicle to the loading platform until payment is made. If payment is made normally, the gas station attendant can disable anti-runaway mode using the remote control. The front and rear rollers are now in restrained mode, ensuring the vehicle can exit normally.

[0037] When the anti-escape function is activated, when the checkpoint blocks the vehicle, the limit motor receives the start-up function signal, starts the motor, and transmits power to the driven gear through the motor drive shaft. The driven gear drives the spur gear structure 3 to move, thereby driving the limit gear structure 4 to leave the inside of the roller limit gear, achieving the release of the fixing effect. In this way, the limit on the rotation of the bearing inner core is released, and the function of keeping the front and rear roller rings in motion is achieved. In this way, when the vehicle rushes through the platform and drives to the front roller ring, although the front roller ring moves with it, the inertia will be maintained, allowing the wheels to continue moving forward and enter the vehicle body load platform. When it is used, when passing the rear roller ring, it will move synchronously with the front roller ring. The wheels lose friction, and the vehicle will be confined to the vehicle body load platform, which makes it easier to prevent escape.

[0038] When refueling, the anti-escape function is activated, and the limit motor receives the activation signal. The starter motor transmits power to the driven gear through the motor drive shaft, which drives the limit member to move through the driven gear, driving the limit gear structure to leave the interior of the roller limit gear, thereby releasing the fixed effect. This releases the limit on the rotation of the bearing inner core, and realizes the function of keeping the front and rear roller rings in motion. In this way, when the vehicle rushes through the approach platform and drives to the front roller ring, although the front roller ring moves with it, inertia will be maintained, allowing the wheels to continue forward and enter the vehicle body load platform. When it is used, when passing the rear roller ring, it will move synchronously with the front roller ring. The wheels lose friction, and the vehicle will be confined to the vehicle body load platform, which makes it easier to prevent escape.

[0039] In addition, the limit motor has a pre-installed remote control and voice recognition module, which can be controlled by voice or voice commands (to avoid unauthorized operation, the voice settings are pre-programmed and require the machine number to be read before release). If a vehicle suddenly encounters a fire near the gas pump while refueling, if the voice content contains key voice information such as "fire, fire, fire extinguisher, leave quickly, occupants leave", it can be released without reading the code, automatically disabling the anti-escape mode and ensuring that the vehicle can be quickly deployed out of the danger zone.

[0040] The automobile anti-escape system of the present invention is reasonably designed and can effectively prevent the automobile from escaping without damaging the vehicle. At the same time, it can be set to be activated or not, which is convenient for operation and disabling. The structure is compact and easy to arrange and install.

[0041] The above is only an illustration of a preferred embodiment of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0042] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
